Subject: [PATCH] ci(e2e-go): unbuffer sed in test pipeline for live log
 streaming

GNU sed defaults to block-buffered stdout when stdout is a pipe
(GitHub Actions runner). Accumulates 4-64KB before flushing, so
test output appeared in sporadic batches unaligned to test
boundaries. -u flag forces line-buffered output so each go test -v
line surfaces in the Actions UI as it is produced.

Side effect: none. No process count change, no SSH session change,
no test execution change. Pure output flushing on the runner host.
